I have many different sizes of nuts and bolts with as many nuts, some course thread and some fine thread. This kit is very handy and easy to use. Nothing to get lost with the case - use one and put it back. Easy. Great product.

This is machined really well and I've already gotten quite a bit of use out of it. No more hunting and searching for the right nut or bolt.

I have been looking at these thread checkers for a while and I decided against the kind that is on a wire. I figured if my son wanted to check threads on a bolt on his truck the wire would be a nuisance. These are aluminum so be careful when screwing them on/on so you don't damage the threads. You know right away whether they fit or not.

Very pleased. Have tried most and they seem spot on. They are I think aluminum so I would not use much force with them but very nice at a good price.
